Abstract
The physical, chemical composition and service properties of imported monolithic
refractory and locally produced refractory lining materials were investigated and
compared in this study. The samples were compacted in a standard rammer, cured
in air for 24 h and oven dried for 24 h. They were then heated to temperature of
100 C and characterized to determine their refractory properties. These samples
were tested for parameters, such as bulk density, porosity, thermal conductivity,
electrical conductivity, refractoriness, permeability, and cold strength. The results
obtained indicate that local acidic ramming mass was found to be a good substitute
to imported ramming masses due to comparative properties of the former. A fusion
temperature of 1620 C was obtained in the local sample which is equivalent to the
value obtained for the imported ramming masses. The results of other properties
show little or no variation between the locally produced ramming mass and the
imported ones.
